*** This bug is a security vulnerability ***
You have been subscribed to a public security bug by Avital Ostromich (avital):
in the last week, the gnome screen locking functionality stopped
working. I'm under the impression this is handled by gdm3, but if not,
please point me at the correct package.
in any case, now there's no lock icon in the power menu in the top
right, win-L does nothing, and trying to invoke manually with the gnome-
screensaver package times out after about a minute with the following
error:
$ gnome-screensaver-command -l
** (gnome-screensaver-command:212161): WARNING **: 18:46:25.014: unable to send
message: Timeout was reached
** Message: 18:46:25.014: Did not receive a reply from the screensaver.
as well, if I suspend the system, on resume it dumps right back to the desktop
without a prompt to re-authenticate, so this is a security issue.
